Router modules
NOTE
When one or more NI-MLX-1GX48-T-A modules are installed in an MLX16-slot router, you must replace the
NI-X-16-FAN-EXH modules with NIBI-16-FAN-EXH-A high-speed fan modules. For more information about high-speed fan
modules, see “NIBI-16-FAN-EXH-A high-speed fan assemblies” on page 39. If the 16-slot router is not upgraded to support
NIBI-16-FAN-EXH-A modules before NI-MLX-1GX48-T-A modules are installed, the following Syslog message is displayed.
SYSLOG: Mar 26 14:19:53:<12>R1, 48X1G modules in slots 10,11,13,16 shouldn't be running without high
speed fans
.
To display information about NIBI-16-FAN-EXH-A modules installed in a 16-slot router, enter the show chassis command.

The output displays firmware Revision A (Rev A) for NIBI-16-FAN-EXH-A modules. Rev A indicates that the router contains the
required rear fan modules to support the NI-MLX-1Gx48-T-A modules. The RPM value thresholds (LOW/MED/MED-HI/HI)
are also displayed for rear fan modules.
NOTE
If the router does not contain NIBI-16-FAN-EXH-A modules, the show chassis command will not display Rev A for rear
fan modules.
